IMPROVEMENT IN WATER-METERS.

Specification forming part of Letters Patent No. [91,03 l, dated May 22,1877 application filed September 9, 1876.

To all whom it may concern Be it known that I, JOHN H. OoNNELL, ofKanawha C. H., in the county of Kanawha and State of West Virginia, haveinvented a certain new and useful Improvement in Water-Meters, of whichthe following is a specication:

My invention relates, rst, to a rotary meter, with pivoted valves,provided with projecting tappet-arms, adapted to come in contact with astop, so as to throw the valves open to their full extent immediately onpassing the induction-opening. The valves rest when closed on rubbercushions, which act to force the wings against the stationary abutmentjust below the inlet, and at the same time yield suiiicient toaccommodate sand or other inequalities.

The invention further consists in the combination with the said pivotedvalves and opening device of a recess within the casing to prevent theobstruction of the valves by sand or other foreign matter, ashereinafter described.

The invention further consists in the combination, with the measuringapparatus, of a faucet, having an intermittent flow of the full capacityof the' discharge-opening, so as to prevent the passage of a minuteconstant stream, which might fail to be accurately measured.

In the accompanying drawing, 'Figure 1 is a vertical section of theapparatus. Fig. 2 is a horizontal section in the two planes indicated bythe lines 2 2 in Fig. 1. Fig. 3 is a perspective view of the rotarypiston and its valves.

A represents the meter-cylinder, and B the rotary piston, which revolvesconcentrically therein. C is the stationary abutment. D is E is thedischarge-port from the meter-cylinder; and F the final discharge-portof the apparatus. G G are a pair of valves pivoted at g to the rotarypiston B. H ISI` are arms projecting rigidly from the heels of thevalves G, so as to come in contact with a stop, 1, directly the valvepasses the inlet D, and thus throw the valve open to its full extent, asshown at the upper part of Fig. 1. a is a recess, in which the extremityof the valve is received, so as to prevent its obstruction by sand orother foreign matter, which may be carried b y the water. After passingthe recess a and stop I the valve is kept open to its full extent by thepressure of the liquid. J are rubber cushions or spr-ings, secured inthe rotary piston B, on which the valves G G rest when closed. Thesprings act to force the valves out, and keep them in close contact withthe incline stationary abutment O, and allow them to yield sufcient topass over any inequalities or dirt. K is the casing of the faucet, intowhich the liquid is received from the conducting-pipe E of the meter.The discharge-pipe F is closed at its inner end by a valve, L, attachedto a lever, M, which is fulcrumed to the case by a pintle, m. Nrepresents .a shaft revolved by a crank or handle, O, and carryingelastic arms or tappets P P, which act in succession on the extremity ofthe lever M, so as to raise the valve L. Q is a bar, extending acrossthe interior of the case in such a position as to receive the contact ofthe elastic arms P P in succession before they reach the lever M. Theobject of this arrangement is to cause the said arms to strike the leverM ksuddenly with such force and in such position that they will deflectthe said lever to fully open the valve before the movement of the arm Pcan be arrested by the operator. R is a pawl engaging with aratchet-wheel, S, on the shaft N, and held by an arm, s, or by a springor weight, so as to prevent a retrograde motion being imparted to theshaft N.

Operation: The drawing shows the valve closed and one of the arms Pdeected by contact with the stopbar Q, and ready to escape therefrom.The additional rotation of the shaft N causes the deflected arm P toescape from the stop-bar Q, strike the end of the lever M, and escapetherefrom, reaching instantaneously the position shown in dotted lines,which permits the lever to resume its normal position, and the valve toclose after delivering a modicum of liquid. A continued rotation of theshaft may cause these discharges to follow each other in as rapidsuccession as may be desired, or the smallest amount of liquid requiredmay beldelivered by a single opening and closure of the valve; but it isimpossible for the operator to open the valve less than to its fullextent. The discharge of the faucet must therefore be in a stream of thefull capacity of the pipe F,-

instead of a stream smaller at first and increasing in size undercontrol of the operator. The faucet can be operated with either a springor weight to raise the valve. Each time the v'alve L opens themeter-pistonB revolves with full force, and the amount of liquid thuscaused to pass is recorded in any usual or suitable manner.

The following is what I claim as new, and

desireto secure by Letters Patent- 1. The combination of the piston B,hinged valves. G cushions J, and stationary abut -E G, of adischarge-valve, L,` opened by a sudden impulse, as explained, so as toprevent the retention of the valve in a slightlyopen position.
